bnx2x: Add init, setup_q, set_mac to VF <-> PF channel

'init' - init an acquired VF. Supply allocation GPAs to PF.
'setup_q' - PF to allocate a queue in device on behalf of the VF.
'set_mac' - PF to configure a mac in device on behalf of the VF.
VF driver uses these requests in the VF <-> PF channel in nic_load
flow.
